摘要：After the October Revolution, those against the Bolshevik regime started to leave Russia, including Russian aristocrats, officials, capitalists and intellectuals. Some of them were exiled to the cities of China. Among them, Shanghai was the largest after Harbin Russian overseas center. Russian emigres in Shanghai managed to create their own cultural life, and some of them were even engaged in literary creation. Thus, Russian emigre literature came into being in Shanghai. In order to have a more comprehensive grasp of Shanghai Russian literature, this thesis provides a general introduction about newspapers, periodicals, publishing houses, art and literary groups, main writers and creation themes of overseas Russians in Shanghai.

摘要：3D computer-aided design (CAD) systems based on feature-based solid modelling technique have been widely spread and used for product design. However, when part models associated with features are used in various downstream applications, simplified models in various levels of detail (LODs) are frequently more desirable than the full details of the parts. In particular, the need for feature-based multiresolution representation of a solid model representing an object at multiple LODs in the feature unit is increasing for engineering tasks. One challenge is to generate valid models at various LODs after an arbitrary rearrangement of features using a certain LOD criterion, because composite Boolean operations consisting of union and subtraction are not commutative. The other challenges are to devise proper topological framework for multiresolution representation, to suggest more reasonable LOD criteria, and to extend applications. This paper surveys the recent research on these issues.

摘要：Cellular vehicle-to-everything(C-V2X) communications is regarded as a promising and feasible solution for 5G-enabled vehicular communications and networking. In this paper, we investigate the pilot design and channel estimation problem in MIMO-OFDM-based C-V2X systems with severe co-channel interference due to spectrum reusing among different V2X communication links. By using zero-correlation zone(ZCZ) sequences, we provide an interference-free pilot design scheme and a corresponding time-domain(TD) correlation-based channel estimation(TD-CCE) method. We employ the ZCZ sequences from the same family set to be designed as the TD pilot symbols and guarantee the pilot sequeneces for neighboring V2X communication links are code-division multiplexing(CDM). The co-channel pilot interference of the deisgned pilot symbols can be effectively eliminated by exploiting the provided TD-CCE method. Simulation results indicate that the accuracy of channel estimation can be effectively improved by the proposed scheme, whose performance is close to that of the non-interference situation.

摘要：As promising candidates for energy-storage devices, supercapacitors （SCs） have attracted considerable attention because of their unique features, such as their high power density, outstanding rate capability, excellent cycling performance, and safety. The recent boom in portable electronic devices requires high- performance SCs that are flexible, simplified, thin, and integrated. Tremendous efforts have been directed towards the design and integration of planar micro- SCs （MSCs） based on different active electrode materials by various methods. This review highlights the recent developments in the device design of flexible planar MSCs and their integration with other electronic devices. The current challenges and future prospects for the development of flexible MSCs are also discussed.

摘要：传统的设计螺旋方法由于割裂了学科间耦合,得到的设计往往是满足设计要求的设计而不是最优的设计。多学科设计优化(MDO)方法正是一种能得到最优设计的新设计方法,MDO目前被广泛应用于复杂工程系统的设计中。文中对多学科设计优化的理论进行了简要综述,在此基础上为了演示MDO方法应用于舰船设计,采用iSIGHT对国外的CGX巡洋舰概念设计的13个模块进行了集成,建立了MDO模型并优化,得到了较好的优化解。在此基础上采用神经网络重新建立了该MDO模型,将优化结果和原MDO模型优化结果进行了比较。

摘要：Substantial effort has been made to search for electrode materials of Na-ion batteries with high energy/power density. The application of S-saturated zigzag MoS2 nanoribbons （MoSzNRs） for Na-ion batteries has been explored through density function theory （DFT）. The theoretical maximum specific capacity reaches 386.4 mAh,g t via dou- ble-side and special edge adsorption mode. The electronic structure reveals that there exists charge transfer between Na and MoS2NRs. The diffusion barrier on MoS2NRs （0.17 eV） is much lower than that of bulk MoS2 （1.15 eV）, indicating an excellent diffusion kinetics, in addition, the S-edge in MoS2NRs plays a key role. Firstly, the Mo edge was half saturated by S, which helps to stabilize the MoS2NRs as well as offer more intercalation sites for Na. On the other hand, Na migrates much faster on the S edge route in MoS2NRs. Our computational results show that S-saturated MoSzNRs exhibit a great potential as electrode materials for Na-ion batteries with high performance.
